1. Which of the following best describes radon and its significance in
residential environmental health?
A. A synthetic chemical used in insulation materials that improves
energy efficiency in homes
B. A radioactive noble gas that can accumulate indoors and is
associated with increased risk of lung cancer
C. A biological contaminant produced by mold growth in damp
environments
D. A harmless atmospheric gas that is regulated primarily for
occupational air quality only
B
Radon is a naturally occurring radioactive gas that can enter
buildings from the soil and accumulate in enclosed spaces, especially
basements. Prolonged exposure at elevated levels is associated with
an increased risk of lung cancer, making it a significant
environmental health concern.
2. In Maryland, radon testing professionals are primarily regulated under
which state framework?
A. Maryland Department of Transportation licensing regulations
, B. Maryland Environment Article governing radiation sources and
radon testing activities
C. Maryland Occupational Safety and Health (MOSH) electrical safety
code
D. Maryland Building Code for residential construction only
B
Radon testing and related regulatory oversight in Maryland fall
under the Environment Article, particularly provisions addressing
radiation sources and radon testing requirements, which establish
rules for testing practices and listed facilities.
3. A “listed facility” in Maryland radon regulations refers to:
A. Any private laboratory that analyzes indoor air samples
B. A facility approved by local county health departments for
environmental testing
C. A radon testing facility included in EPA proficiency program listings
D. Any certified home inspection company offering radon services
C
A listed facility is defined as a radon testing laboratory included in
the most recent EPA National Radon Measurement Proficiency
Program listing, ensuring recognized analytical competence.
4. Which statement best describes a radon testing device under
Maryland regulations?
A. A self-contained digital monitor that instantly displays radon
concentration without analysis
B. A device that collects radon or its decay products and requires
external laboratory analysis
C. A gas detector used exclusively for industrial chemical leak
detection
D. A device that measures humidity levels to estimate radon risk
B
A radon testing device is one that collects radon or radon progeny
and requires analysis by an independent laboratory or measuring
facility rather than producing direct readings internally.
5. What is the primary requirement for individuals engaged in the
business of radon testing in Maryland after EPA proficiency program
, completion?
A. They must perform all testing using self-analyzing devices only
B. They must ensure all samples are analyzed by a listed facility
C. They must submit all test results directly to homeowners without
lab involvement
D. They must discontinue use of charcoal-based testing devices
entirely
B
Maryland law requires radon testing professionals to have samples
analyzed by a listed facility after completing the required EPA
proficiency program phase, ensuring standardized and verified
analysis.
6. Which action is explicitly required when conducting radon testing for
consumers in Maryland?
A. Providing verbal results only to avoid liability
B. Disclosing the test results and the analyzing facility’s information in
writing
C. Reporting only elevated results to state authorities
D. Submitting all test devices to federal agencies for approval before
use
B
Regulations require written disclosure of both radon test results and
the name and address of the analyzing facility to ensure
transparency for consumers.
7. The EPA National Radon Measurement Proficiency Program primarily
serves to:
A. Certify homebuilders in radon-resistant construction techniques
B. Evaluate and list laboratories capable of accurate radon
measurement analysis
C. Provide funding for residential radon mitigation systems
D. Replace state-level environmental regulations
B
The program assesses laboratories’ ability to accurately analyze
radon measurements and maintains listings of qualified facilities for
reliable testing.
